EDWARD BUTT, OF SON'OMA, CALIFORNIA.

RADIATOR.

Application filed April 3, 1922.

To all whom it may concern:

Be it known that I, EDWARD BUTT, a citi- Zen of'the United States, residing at Sonoma, in the county of Sonoma and State of California, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators for motor vehicles and has for its object the provision of a novel radiator in which all the parts are secured together without the employment of solder, the radiator including the usual tubes which are however clamped in position and which may be quickly and easily removed in case of damage and replaced by other tubes withoutrel'no'v'ing the radiator from the vehicle and without services of a skilled mechanic, repairs in this respect and also in other respects being capable of being made at the road side.

An important object is the provision of a radiator of this character in which all the parts are capable of separation and re-assembling in a very short time, the parts being so held together and having such relation that there will be no leakage.

Another object is the provision of a radiator of this character having a cap provided with means for looking it in position and also provided with means for admitting air, the air admission means being designed to be closed in cold weather.

Yet another object is the provision of a novel tool for pulling the tubes when replacement is necessary, the tool not being vitally essential but being of manifest advantage.

An important object is the provision of a structure of this character which will be simple and comparatively inexpensive in coii'st'ruction, efii'ci'e'nt in use, durable in service and a general improvement in the art.

lVith the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the acompanying drawings, in which:

Figure 1 is a front elevation,

Figure 2 is a side elevation with parts broken away and in section, V

' Figure 3 is a vertical sectional view taken on the line 38 of Figure 1,

Figure 4 is a sectional view taken on the line 1- of Figure 2,

Serial No. 549,121.

Figure 5 is a detail section showing the mounting of the tubes,

Figure 6 is a side elevation of one of the tubes and Figure 7 is a View of the tube puller showing it in use.

Referring more particularly to the drawing's I have shown the radiator as compris- 1ng a lower tank member 10 which is provided with the usual water connection 11 with, which is associated a sediment bulb 12 having the usual drain cook 13. Formed on the ui'i'derside of this tank is an extension 14 carrying bolts 15 having nuts 16.

The members 1 15 and 16provide means for attachment upon the chassis of a motor vehiclef The top of the tank is formed with a plurality of threaded holes 17 within which are screwed nipples 18 having angular heads beneath which are disposed packing gaskets 19. The nipples 18 have bores 20 terminating at their upper ends in conical portions 21. Formed at the ends of the upper portion of the tank 10 are laterally extending apertured ears 22 for a purpose to be described.

The numeral 23 designates the upper tank structure which includes a plate 24 formed at its ends with laterally extending aperture'd ears disposed vertically above the ears 22. The plate 241 is formed with threaded holes 26 through which are screwed nipples 27 having angular heads 28 and formed with bores which have their lower ends terminating in conical portions 30. Engaged upon the nipples are lock nuts 31 beneath which are disposed packing gaskets 32. The nipples 27 are disposed vertically above and in alignment with the nipples 19. The upper tank structure further includes a hood 33 bolted onto the plate 24 as shown at This hood carries an upwardly extending filling neck 35 exterior-1y threaded as shown and provided intermediate its ends with a flange 36 for a purpose to be described. The neck further carries a hollow extension 37 through which is slidable a spring pressed plunger 38 for a purpose to be described.

Threaded onto the neck is the "ap 39- which is formed in its lower edge with a notch 40 normally engaged by the plunger 38 for locking the cap against casual rotation so that it will not jar loose and become lost. The cap is provided in one side with a plurality of air admitting holes 41 which are designed to be closed to a variable extent by means of a disk 4:2 mounted within the cap and slidable upon guides d3 therein. Secured against the underside of the top of the cap is a plate 44 at the center of which is swiveled a screw 45 which is threaded through the disk 12. By turning the screw 45 in one direction or the other the disk 42 may be moved to cover the holes 41 partly or entirely as may be desired and as may be found advisable under certain conditions. In cold weather it is intended that the holes be closed and that in warm weather they be opened.

The upper tank structure has the usual water connection 46 which is formed on the plate member 24. The rear edge of the plate member is provided with a threaded socket 47 for engagement of the usual radiator stay rod provided on motor vehicles. The front and back of the radiator are formed as plates 48 provided at their lower ends with lugs 49 engaged through apertured cars 50 which project from the front p the lower and upper nipples 18 and 27 respectively. erably exteriorly grooved as shown at 5 1 for the reception of suitable packing for insuring tight joints.

Extending transversely of the radiator at the center thereof is the main fin or vane 55 through the ends of which extend vertitheir other ends carrying nuts 59 and 60.

engaging against the top and bottom of the ears 22. Disposed between the central fin and the upper and lower tanks are other fins 61 which are spaced apart by spacing sleeves 62 disposed on the stay rods 56. All the fins naturally are formed with holes for the accommodation and passage of the tubes 53. i

.The radiator as above described is highly suitable for use upon trucks, tractors and other motor vehicles where beauty is not a consideration. For use upon pleasure cars it is preferable to provide a shell 63 which encloses the entirestructure except forthe neck 35 and bottom projection '14:, this shell end of the defectivetube has been removed,

These conical ends are prefthe usual slots 66 which are ordinarily provided for the reception of a leather thong which prevents locseness and squeaking or rattling of the hood when the hood is fastened down. The sides of this shell are fur thermore provided with holes through which pass the threaded stems of eyebolts 67 which are engaged upon the stay rods 56 above and below the uppermost and lowermost fins. These eye bolts carry nuts 68 which operate to hold the shell firmly upon the radiator.

l'l' hen the radiator is entirely assembled as illustrated and as above described it is apparent that itoperates in the same manner as any other radiatonthe water circulating from the engine to the upper tank' and then down through the tubes 53to the lower tank 10 and then back to the engine. in the event of breakage of any'of the parts it is apj'ia-rent that the radiator may he disassembled for the purpose of making repairs. In case of freeying or any cause, such as collision or the like which might cause leaking of a tube, it'is'merely neces-' sary to remove the shell and then take off the'hood 33 by removing the bolts 34. The operator asoertains'which tube is leaking and then nnscrews the nipple 27 associated with the upper end thereof and removes this nipple bodily. In order to pull the tube which is-defective it is preferable to make use of the tool shown in' Figure 7. This tool comprises a plate 70through the ends of which are threaded rods 71 having their upper ends formed with eyes 72. The

center of the plate is formed with a hole 73;

through which extends a pair of jaws 74 which are pivotally' connected as shown at 75 and which terminates in barbs 76 de signed for insertion within the upper end of the tube to be extracted. The upper ends of the jaws are formed semi-cylindrical and are exteriorly threaded as shown at 77 for engagement thereon of a nut 7 8 which when rotated in one direction will operateto expand or move apart the free ends of the. aws for gripping engagement within the tubes. One jaw member is prolongedup- 'wardly as shown at. 'Z 9 and carries a handle The spring 81 operates normally to 80. force the jaws together. 4 r Assuming thatthev nipple at the upper the operator inserts the tool into the tube and rotates the nut 78 to cause the free ends of the jaws to expand and bite into the inner periphery of the tube. The rods 71 are engaged upon the top of the plate 24 so that when they are subsequently turned they will cause the tool to move upwardly, carrying with it the tube and thus pulling the tube out of the associated lower nipple 18. A new tube is then placed in position and the nipple 27 is replaced and the nut 31 tightened to maintain the clamping relation, after which the hood 33 and shell 63 are re placed. Regardless of how many tubes may be damaged it may be seen that they are all removed and replaced as above described.

From the foregoing "description and a study of the drawings it will be apparent that l have thus provided a very simply constructed radiator in whichthe parts are all bolted or clamped together so that the use of solder and its attendant disadvantages will be entirely eliminated. Owing to the peculiar construction it is apparent that repairs may be made with utmost ease and without any tools other than a wrench and the tube puller above described. It is apparent that the radiator may be tightened up after long continued use so as to take up any looseness which might result in causing a leak.

lVhile I have shown and described the preferred embodiment of the invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1. A radiator comprising upper and lower tanks provided with water connections,

I nipple members extending through the top of the lower tank and formed with sockets,

other nipple members adjustably mounted through the bottom of the upper tank, and tubes having their ends seating within the respective nipple members, the sockets in the nipple members being conical and the ends of the tubes being conical for confornr ing engagement within the sockets and being provided with peripheral grooves for the reception of packing.

2. A radiator comprising upper and lower tanks provided with water connections, nipple members extending through the top of the lower tank and formed with sockets, other nipple members adjustably mounted through the bottom of the upper tank, and tubes having their ends seating within the respective nipple members, a pair of plates disposed against the frontand back *of the tank members and provided with holes for the passage of air, and means for securing said plates in position, said means consisting of lugs projecting from the lower edges of the plates and engaging within apertured ears extending from the lower tank, and staybolts passing through said plates at the upper corners thereof.

In a radiator, upper and lower tanks each provided at its ends with extensions formed with holes, tins arranged in spaced parallel horizontal position between said tanks, stay rods: extending through the extensions on said tanks and extending through said tins, spacing sleeves on said rods between the successive fins and nuts threaded on said rods above and below said extensions and above and below the upper and lower fins respectively for clamping the parts in position, a shell surrounding the tanks, and eye bolts engaged upon said stay rods extending through the sides of the shell and carrying nuts.

In testimony whereof I afiix my signature.

EDWARD BUTT.
